NOTE: If you want to follow the LFCS articles and learn more for the certification or just to learn more about Linux, then only use the Minimal install. All of these images can be placed on a USB thumb drive with Unetbootin to create a bootable USB device for the install. The Minimal is a NetInstall, but starts with a base system to be added to during installation. The NetInstall ISO allows you to perform the same installation as DVD, but the ISO can be burned to a CD. The DVD ISO file contains everything you need to install Ubuntu on a system. There are three types of downloads: DVD, NetInstall and Minimal.

The main files can be found at specifically go to The files are based off of the processor type your system uses and which type of install you will perform.

To get Ubuntu installed you first need to download the file needed to install the Operating System (OS). You have your choice of three Distribution types and Ubuntu is one of the three. One Linux Distribution used for the LFCS Certification is Ubuntu.
